Income tax returns: Netherlands (The Hague)

I am from India and currently living in Netherlands from last 6 months working in a company as an engineer.

I have two questions related to tax returns-

1. I am getting salary from October'2015, So till march i have got 6 months salary. if my Annual salary is Protected content (Gross) and i only got Protected content for Fiscal year Protected content to March'15), what will be my tax value?Making is more clear, Is my annual salary(Actually received) will be considered Protected content or Protected content for fiscal year Protected content calculation?

2. Is there any difference in income tax if married or living with girlfriend (non married partner?
